The magnetic field is uniform and out of the page inside a circle of radius r, and is essentially zero outside the circular region (see the figure). the magnitude of the magnetic field is changing with time; as a function of time the magnitude of the magnetic field is (b0 + bt3). r1 = 2.4 cm, r2 = 45 cm, b0 = 1.5 t, b = 1.1 t/s3, t = 0.9 s, and r = 16 cm. uploaded image

(b) what is the magnitude of the electric field at location p? (hint: remember that "emf" is the integral of the non-coulomb electric field around a closed path.)
n/c
(d) what is magnitude of the "curly" electric field at location q?
n/c

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
